So I don't have access to any bass tube heads at the moment, but I would really like to capture a more tube-y bass sound. I DO have access to several guitar tube amps though, and I have always been curious- is there any problem with plugging a bass guitar into, say, a Marshall JCM2000, which is then routed to an Ampeg 4x10? If this is safe, will it produce a desireable bass sound? Or is it not safe and something will blow up? Haha.
